If the team and the project are real and working diligently towards the development and the success of the project with a good supporting investors then there are high chances of success. Yes the nature and use cases of the project matters and i like all the projects you have listed and i think they have huge future potential.
They have a potential, but there is also a high probability that the excitement around these projects will pass soon and if you buy them now, you will continue to hold them for another year before you make a profit.
