A: Links from banner vs Content ?
Content, always from the content, google like contextual links 
B: Backlinks from India SEO company do they hurt our link profile?
If you think this backlink could not be good for your domain authority, use Disavow and sleep better, but I would not worry so much as soon as there are just couple of links, variety is also important.
Should I ping my links using tools or have my friends click on them ?
Nah, let them index alone. Patience is very important for SEO 
How many links should I try to build a week ?
Depends on your niche and competitors, im working in a niche with low-medium competence and im creating 10 links / month, im ranking extrem well.
E: Does the position of a backlink matter (in case your able to select position)
I also like to write the backlink in the first paragraph so that google robot follow it as soon as possible, but i´m not really sure if this is a factor xD
F) Link profile
I would not use links on sidebars/footers for a link building factor, but for getting referred traffic interested on your niche. Always nofollow.
