Hope you can advise?
I have 2 sons with 2 PS4.
I have tried to creat a guest account and also a new account however they cannot login at the same time as once one tries to login the other gets kicked. Creating a new account makes content locked on other ps4. Do we have to have 2 ps plus accounts to use the 2 ps4 at the same time?

A guest account is just a sub account, so they won't be able to both play together at the same time. You need two separate accounts, but you only need one PS+ account to allow them to play online together. This also means you only have to buy one copy of digital version of a game for them both to have it installed on their PS4's, and to play that game together online.
Lets refer to your sons as Bill and Bob...
Allocate each son their own PS4, and create accounts for each.
On Bills' PS4, log in using Bobs' account details, and go to the SEN (Sony Entertainment Network) webpage and set that Bills' PS4 as Bobs' primary console. Do the same (opposite) with Bobs' PS4.
When Bob is logged into Bills PS4 he can purchase, download and install a digital version of a game. This means the game is attributed to Bobs' account, and it is also installed on Bills' PS4.
When Bob logs into his own PS4 the game will be available to install on his console, as it was purchased and assigned to his account.
When Bill logs into his own PS4, the game is there for hi to play, because Bob installed it there for him.
Both Bill & Bob can play the game online together at the same time.
As for subscribing to PS+ for online gaming, you only need to pay the subscription once, for one of your sons, but they can both use it. I think this is how I did it...
Do the same as above, get Bill to log into Bobs' PS4 and purchase the subscription. It will then be available for Bob to use on his PS4, as thats the console it was purchased on. When Bill logs into his PS4 he has access to PS+ because it was purchased using his account. They can now both use it together.
I gave my 12yr old son an adult account so he can play whatever game I allow him to play - Call of Duty etc which is an 18 certificate game. Assuming your sons are under age 18, if you create an account for them with their real dates of birth they will be restricted to age relevant games. This may mont ideal now, but as they get older and you trust them they won't be able to play the hames their mates are playing. As a parent you see the log in passwords etc so you can access what they are doing at anytime.
So basically, whatever one son is buying, get them to do it whilst logged into his brothers console.
