Q1) What do you think of the lens choices that I have decided to build my kit?
I think you're making it more complicated than it needs to be. If you are indeed looking at photography as a "social hobby" that you're doing for fun, why make lens selection a major worry? Since you asked, here are my thoughts on your current kit:
17-70mm - A decent walk-around lens, but more limited than it needs to be. I would replace this with an 18-200mm, giving you a very large zoom range and an obvious choice for travel/situations where you "can only have one lens".
85mm - Indeed, a good length for tight portraits (~135mm on 35mm). You may find that a 50mm f/1.8 is a bit easier to walk around with and can still offer a very nice portrait perspective on your camera body.
Q2) Any wide angle lens that you will recommend? (third party or canon) or should I get wide angle zoom lens ?
I've had both the Canon 10-20mm and the Sigma 10-22(?). The Canon was a bit more solid, but both produced acceptable images. The Sigma is significantly cheaper so I'd recommend it based on that alone. I suspect the Canon has subjectively higher image quality, but nothing that makes a material difference at the hobbyist level.
This type of lens is worth having as it opens up a new, almost surreal world of compositions to you. A zoom is your best bet since it will give you a chance to learn about how 10mm differs from 15mm, etc.
Q3) What are your thoughts that I chose all my lens from Third Party instead of Official Canon ones... is that a "smart move"? - Any official canon lens that you will recommend?
At this stage there's no reason to worry about the name on the case. In skilled hands the 3rd-party lenses can be used to make some great photographs - holding an "official" Canon lens doesn't do anything to increase your skill.
That said, Canon's 50mm f/1.8 is a great, affordable lens. They also make an 18-200mm that'd fit the bill for my suggestion above.
Per my initial comment, don't over think this or pay too much attention to the wild claims on the internet. As a hobbyist photographer you should have fun taking pictures and learning - which can be done on any camera/lens combo.
If you decide to take your hobby to the next level then you can start to pick up some superior glass. Until that time spend your time taking pictures and your money on books about photography technique.
