TL;DR Summary
Is there any properties of normalisation that can be used when encountering superstition of wavefunctions
If wave functions are individually normalized does it mean that they are also normalized if phi 1 and phi 2 are integrated over infinity?

Can you explain your question more clearly?
 
The question in the OP cannot be answered, except one has more information on the three wave functions. E.g., if they are orthonormal to each other, then there's a unique answer.

Also the norm in Hilbert space is of course the norm induced by its scalar product. I.e., in position representation, where the Hilbert space is the space of square-integrable functions, this scalar product is defined as
$$\langle \psi_1 | \psi_2 \rangle=\int_{\mathbb{R}} \mathrm{d} x \psi_1^*(x) \psi_2(x),$$
and thus the norm of a wave function is
$$\|\psi \|=\sqrt{\langle \psi|\psi \rangle}, \quad \langle \psi|\psi \rangle=\int_{\mathbb{R}} \mathrm{d} x |\psi(x)|^2.$$

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In her YouTube video Bell’s Theorem Experiments on Entangled Photons, Dr. Fugate shows how polarization-entangled photons violate Bell’s inequality. In this Insight, I will use quantum information theory to explain why such entangled photon-polarization qubits violate the version of Bell’s inequality due to John Clauser, Michael Horne, Abner Shimony, and Richard Holt known as the...
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...
I asked a question related to a table levitating but I am going to try to be specific about my question after one of the forum mentors stated I should make my question more specific (although I'm still not sure why one couldn't have asked if a table levitating is possible according to physics). Specifically, I am interested in knowing how much justification we have for an extreme low probability thermal fluctuation that results in a "miraculous" event compared to, say, a dice roll. Does a...
