There are many coin like bitcoin. ETH, lTC, BCC, RFR, GRG. It,s not value equal to bitcoin but growth rate is high.
Yes you are correct. Many altcoins now in the market but I don't see any of them reached same with the value of bitcoin. But maybe in the future and I don't really know when, that some of the altcoins will get in progress that may rival bitcoins in its popularity. For instance like ethereum, ripple, litecoins and bitcoincash and so many others including that you mentioned, these may have great possibilities to become like bitcoin in the future.
