Hi friend, first of all you may relax and not be offended if people don't reply immediately, or not at all.
I may not be the most prestigious evaluator you can get, nor am I familiar with the Indian market, but I suggest you chose myonlinemarket because onlinemarket was obviously taken.
This reminds me of myself running into domains and putting a '24' at the end or a 'my' at the start if my desired keywords where already gone.
Of course this can work out as well in many cases (I reg'd weedstore24.com and still do like it), but surely it decreases the value of your name significantly.
mybusiness.in, which is an enormous keyword, sold for only 210 USD five days ago.
Regarding the second one there is a Nexus Racing Club in the US for Horse Racing and of course it's common in the motorsports business, but here "racing nexus" would be spelled the wrong way round. Last but not least there are Racinggame Apps on the Google Nexus, for which there doesn't seem to be a real demand according to search volumes.
Not sure if there are trademarks on it either, but that is another thing you may check in the first place when acquiring domains.
Ask yourself who could be a potential buyer for your domain and why. Research the markets and business niches your keywords are relevant to.
Get an impression of possible sales by checking your extension and keywords at namebio.com.
No doubt there are a lot more private sales which won't ever be listed anywhere,
but still you get an idea of what may be possible on the common domain market platforms.
Have a drink and use this great place to read and learn about researching and carefully choosing names you register.
P.S. myonlinemarket.in mid to high xx$, telugublogger.in - understood equally to englishblogger.co.uk - maybe low to mid xx$ to an interested / really interested blogger. racingnexus.com can be 0$ if there are trademarks on it to anything, personally I don't see much value. No guarantees, as luckily in the end you never know until you tried
Cheers!
