Hi,
There is no locking period for ALCX single-sided staking, but the tALCX pool, where ALCX is routed via the ALCX Token Reactor in Tokemak, imposes a maximum 1-day lockup (to be extended to 1 week in future).
For the APR on ALCX staking, you can see if on the Alchemix dApp, on the Farms page (https://app.alchemix.fi/farms). Note that you need to have your wallet connected to see the APR.
In terms of help with staking, I'd encourage you to join the Alchemix Discord (https://discord.gg/alchemix). In the #support channel you can get some help. Beware however unsolicited DMs - don't respond to those.
