Frogs and toads will find their way if you make a pond but be sure it has a sloping edge or a plank or stone they can use to climb out again. Both like to come out onto dry or boggy land and toads especially don't spend their life in there but need it for breeding. Both will eat pests such as slugs. Don't put fish in the pond as they will eat the spawn.
Hedgehogs need access so a solid fence or wall will keep them out. You can cut holes in wire mesh or wooden fences to allow them to get to and fro but your neighbours will have to do the same and also provide safe cover for them to feed and breed and raise their young and hibernate.
Birds will come if you provide food all year round - peanuts in feeders, fat balls, loose seed for ground feeders and in hanging feeders for the "swingers" such as tits and sparrows.
Planting flowers that attract insects will also attract birds which will eat aphids and caterpillars for you.
