[Tex/LaTex] Subfigures side by side with captions

captionssubfloats

I am using the following code to put my two figures side by side with different captions,

\begin{figure*}[t!]
    \centering
    \begin{subfigure}[b]{0.5\textwidth}
        \centering
        \includegraphics[height=1.2in]{a}
        \caption{Lorem ipsum}
    \end{subfigure}%
    ~ 
    \begin{subfigure}[b]{0.5\textwidth}
        \centering
        \includegraphics[height=1.2in]{b}
        \caption{Lorem ipsum, lorem ipsum,Lorem ipsum, lorem ipsum,Lorem ipsum}
    \end{subfigure}
    \caption{Caption place holder}
\end{figure*}

I get the following output: output

However, I want to position both my images vertically same line, like the following:

Desired output: desired

Use the t option for the alignment of the subfigures:

\usepackage{subcaption}

\begin{figure*}[t!]
    \centering
    \begin{subfigure}[t]{0.5\textwidth}
        \centering
        \includegraphics[height=1.2in]{a}
        \caption{Lorem ipsum}
    \end{subfigure}%
    ~ 
    \begin{subfigure}[t]{0.5\textwidth}
        \centering
        \includegraphics[height=1.2in]{b}
        \caption{Lorem ipsum, lorem ipsum,Lorem ipsum, lorem ipsum,Lorem ipsum}
    \end{subfigure}
    \caption{Caption place holder}
\end{figure*}

Using this, both images will be aligned on top:

[Tex/LaTex] Setting position of figure, captions using sidecap

I would suggest you to use the more powerful and flexible floatrow package instead; it allows you to easily customize the caption position per figure; a little example using the a0poster document class and some of the settings of your document.

The example shows three three figures; the leftmost one has its caption to the right; the middle one has the caption below the figure, and the rightmost figure has the caption to the left; of course, you can change the lengths used according to your needs:

\documentclass{a0poster}
\usepackage[demo]{graphicx}
\usepackage[capbesideposition={bottom},facing=yes,capbesidesep=quad]{floatrow}
\usepackage{lipsum}% just to generate text for the example
\usepackage{textpos}

\TPGrid[10mm,10mm]{122}{100}     % e.g., 3 cols width=40, plus 2 gaps width=1
\parindent=0pt
\parskip=0.5\baselineskip
\setlength\fboxsep{0pt}
\setlength\fboxrule{0.5pt}

\begin{document}

\begin{textblock}{40}(0,8.2)
\lipsum[3-11]
\begin{figure}
\thisfloatsetup{capbesideposition={bottom,outside},capbesidewidth=15cm}
\fcapside[\FBwidth]
  {\caption{some text here to represent the caption for figure one}\label{fig:testa}}
  {\includegraphics[width=10cm,height=6cm]{image1}}
\end{figure}
\end{textblock}

\begin{textblock}{40}(41,8.2)
\lipsum[3-11]
\begin{figure}
\floatbox{figure}[3\FBwidth]
  {\caption{some text here to represent the caption for figure two}\label{fig:testb}}
  {\includegraphics[width=10cm,height=6cm]{image3}}
\end{figure}
\end{textblock}

\begin{textblock}{40}(82,8.2)
\lipsum[3-11]
\begin{figure}
\thisfloatsetup{capbesideposition={bottom,inside},capbesidewidth=15cm}
\fcapside[\FBwidth]
  {\caption{some text here to represent the caption for figure three}\label{fig:testc}}
  {\includegraphics[width=10cm,height=6cm]{image3}}
\end{figure}
\end{textblock}

\end{document}

The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.

Since you are using the textblock environment, the floating mechanism is disabled so the usual placement specifiers (e.g., [!b] or [!hb]) won't have effect here; as far as I know, you'll have to adjust the vertical positioning manually.

[Tex/LaTex] Multiple Figure Numbering and Multiple Captions for Figures

caption and subcaption package give you the freedom to choose what format you desire for your captions and subcaptions.

For question 2 (if I correctly understood) you need a "multiple" subcaption for a unique image, I've done that with a tabularx of subcaptions, playing with the subfigure counter (with the help of egreg and Arash Esbati).

\documentclass{book}
\usepackage{graphicx}
\usepackage{array}
\usepackage{tabularx}
\usepackage{makecell}
\usepackage{caption}
\usepackage{subcaption}
\DeclareCaptionLabelFormat{onlynumber}{#2}
\DeclareCaptionLabelFormat{Anumber}{A#2}
\DeclareCaptionLabelFormat{3number}{3#2}
\DeclareCaptionLabelFormat{Hnumber}{H#2}
\captionsetup{labelfont=bf,labelformat=onlynumber,labelsep=space}    
\captionsetup[sub]{labelfont=bf,labelformat=simple, labelsep=newline}    
\renewcommand\thesubfigure{\arabic{subfigure}}%subfigure number numeric

\usepackage{mwe} % only to create blind text and example-image
%\usepackage{showframe} % for testing purpose only
