Need to operate a timer with a remote Answered

I have a 6 Volt radio frequency remote control pair and a separate board with a 5 to 12 Volt timer circuit that turns power off to a load after 1 to 300 seconds. The timer circuit uses capacitors and resistors including a variable resistor plus a 555 too plus jumpers from Amazon.com to see a picture,it lists as: GEREE Timer Relay Switch 1-300 second 5V 9V 12v DC input TIME OVER RESET Delay.
Will it work if I connect the RFRC to power and then from there wire to the timer and then wire the timer to my load so that I can remotely make the timer circuit  operate my load for the set time?
I ask so as not to burn a thing that takes weeks to get.
Will the 1 channel remote control receiver's single relay reset back into a NO condition from NC after current stops flowing from the battery power and through he remote control's 5 pin relay into the capacitor(s) of the timer circuit, that is to say, will the remote relay reset to NO after the timer's single relay goes back from NC to NO after the capacitor(s) run out of charge?
As a note, I have had very little success finding a remote controlled timer in the 6 Volt range. 12 Volt remotes with timers are easier to find but that is too much power, size and expense for my application.
Know of a supplier?
If I have enough of this correct to make sense then any wisdom in this matter will be greatly appreciated.
Thank you,

Vince you need to make a decision on which voltage to standardize 12v, 6v or 5v and make all parts work at that voltage.

I would choose the voltage of your relay coil as the standard.

Thank you for the reply.
The relays on both the remote and the timer are stamped 5 Volt DC.
I assume this to be my decision on a standard.
I need the 6 Volt solenoid for enough flux to get the minimum 7mm throw distance required. That is to say, I have not found a lower Voltage solenoid that can attain the throw travel distance needed.
Maybe an in line capacitor could be added for a fast pulse to bring the solenoid plunger in and the weaker Voltage from the relay to hold it in?
The 5 Volt relay coil begins to operate at lower Voltage than the 6 Volt solenoid and I am hoping the solenoid will work and pull in 7 mm at the delivered 5 Volts for 5 seconds.
The timer can withstand a range from 5 to 12 volts because there is a voltage regulator in line before the 5 Volt relay.
I have been, and plan to use dry cell AA rechargeable Nimh batteries ranging from 1.38 Volt fully charged and rated at 1.2 Volts each to whatever they drain down to and so I thought it necessary to deliver a minimum of 5 up to 8.38 Volts as a range since batteries get weaker with time.
Honestly since I am educated in electronics only through what I am able to find, read and understand online I may be missing a crucial reality that I may not ever operate a solenoid designed for 6 Volts on a 5 Volt standard. My thought from what I have read is that the solenoid will operate but have less force but force is not an issue just the throw distance.
Any thoughts on this?
Experimentation is somewhat expensive and frustrating.
Like mathematics, I note that electronics has many corridors leading to the same level so I seek an answer given I have not paid sufficient dues.

So while the relay coil is 5 volts the contacts can handle a higher voltage and current. Simply run the solenoid plunger on 12 volts.
