I don't know the layout of Stansted - if I choose the second option do I just follow signs for Transfers?
The reason you are getting the answers aboeve is that Stansted does not have a 'transfers/flight connections' channel for international to international flights, in the same way that most airports do.
Can you change your easyJet flight to arrive earlier or your Ryanair flight to leave later?
That would be the best option for peace of mind.
