You can put sound cards, raid controllers, capture cards, wireless adapters, tv tuners or a second NIC etc.
You don't need to worry about that. Unless you already have any you won't be buying legacy hardware now that only works on PCI 1. You may want to look into sound card if you have studio quality equipment and have need for better audio. I recommend Gigabyte Gaming 3 b350 motherboard over this one if audio is priority as it comes with better audio codec and circuitry.
Ths suggested configs are good but I'd suggest, getting the GTX 1060. If budget is problem, you may want to look into Ryzen 1600 which saves ~7k on processor+cooler.
See, clock to clock and core to core, Ryzen equals Broadwell. But hey, Ryzen 5 has 2 extra cores and 8 extra threads compared to the latest Skylake i5. Ryzen 5 simply destroys the latest i5 in overall performance.But in some forums , people suggest that Ryzen architecture is equivalent to Intel old Broadwell architecture . So go for core i5 .
You can put a X1 or X4 card in a X16 slot and it will work completely fine.I asked this becuase , in future if I bought a peripheral with PCIe x1 / x4 slot , can I able to fit it ? That is does this motherboard support all PCIe x1, x4 peripherals ? (because the x1 and x4 slot pictures in internet is smaller )
I am not going to use mutli GPU configs

Asus Prime B350 Plus is one of the best B350 motherboards available, you can check these motherboards as well.
ASUS B350 F GAMING
GIGABYTE AB350M GAMING 3
ASROCK AB350 GAMING K4
MSI B350M GAMING PRO CARBON
MSI B350 KRAIT GAMING
Last two motherboards are only available on newegg.com online might not be launched in india but are top motherboard.
Asus Prime A320M-K -5165.I like all these motherboards. But the cost seems to be higher for my budget (above 8,500). Will you suggest a Ryzen motherboard below 6,000 which have atleast 2 USB 3.1 Gen 1 ports at back and 2 USB 3.1 Gen 1 ports headers
