Your code contains invalid column specifications. Instead of {1cm} you maybe intended to use p{1cm}. However, if I add the missing letters to make the code compilable, I don't get the output you show in your question as the first column is very narrow. Changing the column specifier of the first column to p{7cm} or something else and the last three columns to c type columns gives us a result that is close to the screenshot.

The missing vertical lines are caused, because the second row of your table misses three &signs. If you add them, the vertical lines will be complete. However, if you use p type columns, there is no need for manual linebreaks. See first table in my MWE.

If you nevertheless insist on manual linebreaks inside of table cells, use \newline insead of \\. To horizontally center the text in the first column, use >{\Centering}p{7cm}. If you also want vertically centered, text, replace p by m. (See second table in my MWE).

Personally, I would suggest a different layout using the tabularx package for an X type column that automatically calculates the width of the respective column so that the whole table is as wide as a specified widht (textwidth inn my example). Also I'd avoid vertical lines and replace teh horizontal lines by rules from the booktabs package. (See third table in my MWE):

enter image description here

\documentclass{article}

\usepackage{array}    % Needed for the second example.
\usepackage{ragged2e} % Needed for the second example.

\usepackage{tabularx} % Needed for the third example.
\usepackage{booktabs} % Needed for the third example.
