The first looks like an ovolo moulding (without the lower lip), the second a bullnose or rounding over bit is required. You will have to work out the radius for a close match. Depending on the thickness it would would wise to consider cutting it in a router table rather than free hand (if possible), and in any event to use a half inch router shank. Do not try unless you have built up some practical experience in the use and maintenance of routers and routing.

Blup
 
a very large roundover bit and a quirk or even a panel bit and a router table if its not a constant curve
 
I have done some routing but I am not super competent. I have a Makita RP2301FCXK/2 1/2" Plunge Router but no router table. If I do it at home I'll need to do it freehand, using the guide that comes with the router. There is a workshop near me that I can go to that might have a router table.

Just to give more detail regarding the project I am doing; I am changing my existing floorboards with nicer, thicker, and wider boards, see the pic below. I'd like to use a narrow long piece of the same floorboard as an edge (is there a specific name for that bit?) on the stairwell side. I would like to route the outer bit of this edge bit with a bullnose cutter like this one to make it look nice and match the stairs tread edge. I do hope this makes sense. Does this sound like a good way of doing it or is there a better way?

It is possible to make a DIY router table by basically fixing a plunge router upside down in a piece of laminated chipboard. Then make an upstand out of similar material that can be moved closer/ further away.
There are several videos on YouTube

needless to say- take care if you don’t want to gain the name “stumpy”. Even machine shop spindle routers are bloody dangerous. Home made could be even more so.

you can buy base plates for some routers to help
 
how thick are the boards or bullnose ??
one pass on the top and one pass on the bottom take the board thickness say 22mm deduct 3mm that gives you 19mm half that is 9.5mm so get that radius as you need a 3mm flat on the nose to run on

if you are cutting say a 30mm wide bit off timber then get say 69mm wide bit off timber run along both edges top and bottom then cut in half

Grand! That sounds like a plan. But it looks like the router cutter I need is out of stock. Bugger!

if its 21-22mm timber yes although wealden tools own cutters tend to be cheaper
although that one has a quirk/step you need one with the bearing flush if you want a bull nose

Yes, I would buy it from them buy it from Wealden but it is out of stock. I'll email to ask when they are due to have it again
 
you wont get a bull nose with that cutter you will get a step you need a cutter where the bearing is exactly the came size as the the cutter

The small print says that the cutter comes with two bearings, one creates the step and the second one is for rounding off
