Hey, there are multiple subparts posted, we are authorized to answer three subparts at a time, since you have not mentioned which parts are you looking for, so we are answering the first three subparts, please repost your question separately for remaining subpart.

Step 2 free body diagram of block-1

Physics homework question answer, step 2, image 1

 

Step 3 1) Weight force on a block-1

weight of block by earth is given by following formula;

W1=m1g                                                                           1)

where,

m1=mass of block-1

g=Acceleration due to gravity

Values given in the question are as follow;

m1=5 kgg=9.8 m/s2

Substitute known values in equation-1);

W1=5 kg×9.8 m/s2W1=49 N

Hence,

W1=0i⏜ N-49j⏜ N

Weight is exerted on a block in downwards direction.
